Home Page Featured Image Alignment

So if I create a page, I can select “Blog Image Medium” from the Templates under Page Attributes, and then I added:

.medium-wrap .post-featured-image {
	float: right;

under Custom CSS. I get the desired effect- the thumbnail on the image is shown on the right of the title and text preview. However, I can’t figure out a way to do this with the home page since it is not listed under my Pages tab. The only pages shown here are the ones I created, but not the default home page.

When I view my home page, the featured images are centered on the screen, and I want them to be aligned to the right. How can I do this?

Please read theme documentation and pay a closer attention to “10. How to set up Blog Page”. It will explain exactly what you are looking for.
